The regexp can either be supplied - when the QRegExpValidator is constructed, or at a later time. - - When QRegExpValidator determines whether a string is \l Acceptable - or not, the regexp is treated as if it begins with the start of string - assertion (\b{^}) and ends with the end of string assertion - (\b{$}); the match is against the entire input string, or from - the given position if a start position greater than zero is given. - - If a string is a prefix of an \l Acceptable string, it is considered - \l Intermediate.
